new and useful Improvement ijn Radiators,-

of which the following is a specification.

This invention relates to heating coils or radiators and relatesparticularly to heating coils or radiators of the type comprising aheader, the interior of which is divided into compartments by apartition, radiating pipes secured in an outer wall o f said header theinner ends of which arein open communication with one compartment ofsaid header and the outer ends of which are closed, and open-ended pipessecured in the partition wall of said header, which extend into theradiating pipes securedv in Asaid header, the attached ends of which arein open communication with the compartment of the lheader other thanthat with which said outer radiating pipes communlcate.

The object of the invention is to provide a header for a radiator of thetype specified,

constructed and arranged for effectively drainingl itself .of water ofcondensation.; and in which, also, the steam entering the header willoperate to maintain the water of condensation at a suiciently hightemperature to prevent it from freezing even in very severe weather.

To effect the objects of the invention, a radiator of my inventioncomprises the va.- rious features and details of construction thereinafter described and claimed.

In the accompanying drawing, in which my invention is fully illustrated,

Figure 1 is a side view of my improved radiator, showing the header anda portion of the pipes 'or tubes in section, *the header being disposedhorizontally.

Fig., 2 is a line 2-2 of Fig. 1. A

Fig.'3 is an end' view thereofl from the position 3-3 of Fig. 1. w

Fi 4 is a sectional end view the vllne 4-4 of Fig. 1.

Fig. 5 is aside view, partly iny section, of

thereof on a radiator embodying my invention, show- .f

ing` the header disposed vertically; and

ig. 6 is a fragmentary view of the end of 'the radiator remote from theheader thereof.

plan section thereof onjthe Referring now particularly to Figs. 1\ to 4of the'drawing, A designates the header of a radiator of my invention,the interior o f whlch is divided by a longitudinal par` t1on A intocompartments a., a.

. As shown, said header A is disposed horizontally and secured in thetop wall 1 thereof are tubes 2, the inner ends of which are 1n opencommunication with the compartment a of said header and the outer endsof which are closed; and secured in the partition A are open endedtubes?) which arel smaller than the inside diameters of thel tubes 2 andextend into said tubes, being preferably of such length that they willextend to w1th1 n a short distance of the closed ends ofsald tubes 2.Both ends of the tubes 3 bemg open, said tubes thus connect thecompartment af of the header with the interiors ofthe tubes @adjacent totheir outer, closed ends and, through said tubes 2, with the compartmenta ofsaid header A.,

The pipes 2 are of proper'size to provide adequate heating surface andto produce a desired velocity of steam circulation there- 1n to secure'efficient and economic operating conditions. l l

Formed at one end of the header A is a chest 4 the interior of which isdivided by an. angular wall 5 into chambers 6 and munication with thecompartment a of the header'A and is adapted to be connected by a pipe 8with a Asource of steam supply, not shown, and the chamber 7 is in opencommunication with the compartment a of the header A and is providedadjacent to itsv bottom side with la drain connection 9. .Toy providefor draining the steam compartment a of said header and the chamber 6 ofthe chest'4, saidchest 4 preferably extends below the bottom wall ofsaid header A and the chamber 7 of said chest is extended beneath the,bottom wall of the chamber 6 and is connected with said chamber 6 bymeans of a drain hole 10 formed in the bottom wall of said chamber 6.Preferablythe bottom of the chamber 6 is below thebottom of thecompartment a', whereby water 'of .condensation accumulating in thechamber 6wi1l form a water seal for the drainage openingv 10, thuspreventing the escape of steam from the chamber '6 to thev drainagechamber 7. It is lfound in practice that, due to .the low steam presiamessie sure used in radiators of this type, an effective seal can beprovided by making the drainage hole 10 of small size.

ln practice, l eect the object of my invention as it relates topreventing freezing of the water of condensation in severe weather, bythe angular shape of the partition wall 5, whereby the returncompartinent of the chest 4 extends on two sides of the steamcompartment 6,. thus providing a relatively large radiating surfacemaintained at a high` temperature by the steam entering the compartment6, which will operate, in an obvious manner, to maintain the water ofcondensation contained in said return compartment at a correspondinglyhigh temperature, and will effcctivelyprevent freezing thereof under allusual conditions of use.

ln the preferable construction shown, both the upper side of thepartition A- and the inner side of the bottom wall of the header Adecline toward the chest 4, so that all water of condensation will drainfrom both of said compartments a and a into said chest, the water ofcondensation from the compartment a passing directly into the chamber 7while that from the compartment af passes first into the chamber 6 andthence through the drainage hole 10 into said chamber 7. j

To'prevent the air from becoming trapped in the radiator, which wouldprevent the steam from circulating therethrough, said header ispreferably provided with a usual air vent, consisting, as shown, of ahole or.

opening 11, formed through the top wall of the drainage chamber 7 of thechest 4 of said header.

My improved radiator may be supported by any desired or approved means,being preferablyl supported in such manner that it may expand andcontract freely without being subjected to any stresses therefrom, therelation being preferably such that the top side 1 of the header A willextend substantlally horizontal and the bottom wail of said header andthe partition Af will decline at a desiredv angle toward the chest 4.

As shown, said radiator restsloosely, adjacent to its ends, 'on theupper edges of inverted T-bars 12 and 13, the bases of which are securedto the floor or other supporting surface.

vSaid radiator is confined in position on said T-bars 12 and 13 bytransverse ribs 14 formed on `the under side of said header A, outsideof and closely adjacent to which the Tebars 12 and 13 are designed to bepositioned. whereby contact of said ribs 14 with the upper ends of saidT-bars will limit the movement of said header A.

In the installation of radiators, it frequently happens that thevertical space available for the radiator is limited, while theavailable horizontal space is practically unrestricted, thus renderingit necessary to conform the Vertical dimension of the radiator to thevertical space available and to correspondingly increase the horizontaldimension of the radiator, in order to provide the necessary radiatingsurface.

A radiator embodying my invention is particularly well adapted for useunder the conditions described, its application merely requiring theinstallation of the header A in upright instead of horizontal position,as shown in Figs. 1 to 4, and securing the circulating pipes therein sothat they will project horizontally therefrom, said header being made ofa height to conform to the vertical space available and the heatingpipes of any length necessary to provide necessary `radiating surface.

This application of my invention is shown in Fig. 5 of the drawings, inwhich A2 designates the header as a whole, supported in uprightposition, and secured in and projecting horizontally from which are theouter and inner tubes 2 and 3 which communicate, respectively, with thecompartments a2 and a3 of the header, the outer ends of the tubes 2being closed and both ends of the tubes 3 being open.V

As regards all of its essential features and excepting minor detailshereinafter described, the radiator shown in Fig. 5 is identical inconstruction with that shown 'in Figs. 1 to 4 of the drawing and will bepartment a3 of the header through a steam sup-ply pipe 8 which opensthrough a lateral wall of said header and the chest of the header A2,designated 4', is provided-with drain and vent openings 9', l0 and 11'corresponding to the drain and vent passageways 9, 10 and 11 shown inFigs. 1 to 4, but the position of which is changed to correspond to thechanged position of said header.

The outer ends of the pipes 2' are supported by upright plates 15 formedin which are holes 16 adapted to receive said pipes 2. Said plates 15are supported in upright position by angles 17 at the lower edgesthereof, which are secured to the Hoor by means of lag screws or thelike. The number of supporting plates 15 may be varied'as may beconsidered desirable or necessary to properly support the pipes 2.

For purposes of convenient reference and in order to distinguish thecompartments of the headers and the chambers of the chests, thecompartments a, a2 of the headers will be designated in the claims,return compartments, and the compartments a, a3, steam compartments.And, in like manner, the compartments 6 and 7 of the chest will bedesignated in the claims as the steam and return compartments thereof,respectively.

I claim: y

l. A radiator com rising a header and a chest, partitions winch dividesaid header and chest into steam and return compartments, thecompartmentsof said chest communicating, respectively, with differentcompartments of said header, pipes which connect the compartments ofsaid header, and a pipe which communicates with one compartment of saidheader and is adapted for admitting steam thereto, the relation beingsuch that the compartments of said header will drain into thecompartments of said chest with which they communicate, respec tively,and the compartments of said chest being provided with drainagepasageways, the drainage passageway compartment being formed inthebottom wall thereof and discharging into the return compartment ofsaid chest, the bottom of the steam compartment of said chest beinglower than the bottom of the steam compartment of the header` therelation being such that therwater which drains into said compartmentwill form a water seal for the drainage passageway from they steamcompartment of said chest, substantially as described.

2. A radiator comprising a header and a chest, partitions which dividesaid header and chest into steam and return compartfrom the steam ments,the compartments of said chest communicating, respectively, withdifferent compartments of said header, pipes which connect thecompartments of said header, and a pipe which communicates with onecompartment of said header and is adapted for admitting steam thereto,the relation being such that the compartments of said header will draininto the compartments of said chest with which they communicate,respectively, and the compartments of said chest being provided withdrainage pasageways, the drainage passageway from the steam compartmentdischarging into the return compartment of said chest, the returncompartment of said chest extending on two sides of the steamcompartment thereof, whereby steam entering the steam compartment ofsaid chest will maintain the water in the return compartment of saidchest at a suficiently` high temperature to prevent freezing thereof,and the bottom of the steam compartment of said chest being lower thanthe bottom of the steam compartment of the header, the relation beingsuchv that the water which drains into said compartment will form awater seal for the drainage passagewayfrom the steam compartment of saidchest, substantially as described.
